I am not a PHP programmer, but i assume it would not be to complicated to integrate on the test page a check box "send test to all emails", instead of the need to type in single emails.Alernatively a larger input text field (i.e. 5 lines) with all emails listed, so that someone can choose one to 'N' email subscribers.

The idea behind that is that i abuse your tool for sending newsletters which are not automatic, as i am changing a text in an existing post, but i am not creating a new post. This feature request would give me less pain sending those "newsletters"/updateletters to my subscribers and it may help also others to test email post in larger test groups before going live with a solution. As i said, for somebody who know PHP and the Plugin it i probably a no brainer to integrate this and i would appreciate it a lot!

Third - my offer

... as i said, i cannot help you with the PHP integration, but i read that you search help for the documentation. I could do probably the english version, but more likely 'die deutsche Version', as this would be my native language ;)

There will be newsletter support in PN 2.0. But at the moment, I'm having trouble to find time to do the coding. Until then it's probably better to get one of the many Newsletter-mailers out there. There are really good ones.
